Mary Elisabeth wakes up several times a week in a state of fear and panic. She can't move - feels totally paralysed - and feels like someone is pushing her down onto the bed. She can't breathe and feels like she is having a heart attack. And she senses an evil presence in the room. Is an evil spirit or a demon attacking her during sleep, or trying to possess her? Here is my answer. Thank you SO much for your question, Mary Elisabeth - this is something which I have encountered in clients many times up through the years as a psychologist and as a medium.
